MBSA Supplement Tool to Help Enterprises Catch MSN Messenger Flaw

Microsoft on Tuesday released a special Enterprise Update Scan Tool to help organizations find computers vulnerable to an MSN Messenger flaw that the Microsoft Baseline Security Analyzer (MBSA) would miss.

The MSN Messenger vulnerability is among five critical bulletins Microsoft released on Tuesday. An attacker could exploit the flaw to take complete control of a user's system.

Microsoft creates stand-alone Enterprise Scanning Tools in patch cycles when MBSA or the Office Detection Tool would not discover systems vulnerable to the underlying flaw in a security bulletin. The company posted previous Enterprise Update Scan Tools in February and October.

More information on the April Enterprise Update Scan Tool is available here.
